Question

How many tissues should a package of tissues contain? Researchers determined that 51 tissues is the average number of tissues used during a cold. Supposed a random sample of 10,000 tissues users yielded the following data on the number of tissues used during a cold: x̅ = 40, s = 21. Suppose the corresponding test statistic falls in the rejection region at a=.05 what is correct solution?

A)AT A =.05 ACCEPT Ha

B) AT a=.10 reject Ha

C) At a=.10, reject Ho

D0 aT A=.05, reject H0

Answer 1

If test statistic falls in the rejection region at 0.05 significance level, we can conclude that:

At A=.05, reject H0

Option D is correct.
